Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668478, here are decompositions:

19 + 8668459 = 8668478
97 + 8668381 = 8668478
109 + 8668369 = 8668478
199 + 8668279 = 8668478
211 + 8668267 = 8668478
271 + 8668207 = 8668478
277 + 8668201 = 8668478
337 + 8668141 = 8668478

Showing the first eight; more decompositions exist.
